I have a 99 chev sub 1500 350v8 that keeps giving a o2 sensor code of 041. I replaced sensor and the code disappeared. Took vehicle to have state inspection and 041 code was back on. replaced sensor again with a new one and 041 code is still there. Any ideas ? Bill Baton Rouge LA
Code P0041 is most likely a wiring problem. Check for opens, shorts and damaged wiring going to the oxygen sensors. Also check to make sure the plugs for the upstream and downstream oxygen sensors haven't been switched by mistake. If all this checks out ok the computer is most likely bad. HTH. -Jim
